Ora is one of the select performers chosen to appear at the one-time concert being held at St Peter's Basilca in Rome on September 3, the day before Mother Teresa will officially be declared a saint.
Speaking on The Tonight Show Starring Jimmy Fallon on Ora said, "I looked at the guest list and I saw Pope! It's a real honour and I don't know if anyone's done the whole Vatican venue thing before, it's a bit interesting that the Vatican's someone's venue but it's going to be fantastic.
